Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659742, here are decompositions:

31 + 8659711 = 8659742
73 + 8659669 = 8659742
79 + 8659663 = 8659742
199 + 8659543 = 8659742
211 + 8659531 = 8659742
229 + 8659513 = 8659742
241 + 8659501 = 8659742
271 + 8659471 = 8659742

Showing the first eight; more decompositions exist.
